Scala & Spark-Master Big Data with Scala and Spark - Final Run - Functions

The video tutorial covers the importance of structuring code into smaller, reusable functions. It demonstrates a test run in an IDE, focusing on user credential verification and transaction operations in an ATM simulation. The tutorial explains how to handle incorrect inputs, perform balance checks, withdrawals, deposits, and exit the system using loops and conditional statements.

What is the primary benefit of breaking code into smaller functions?

• It increases the complexity of the code.

• It enhances code readability and reusability.

• It makes the code run faster.

• It reduces the number of lines of code.

What happens if incorrect card information is entered in the ATM system?

• The user is locked out permanently.

• The system shuts down.

• The user is prompted to try again.

• The system accepts the incorrect information.
